180 - 360/N I think. The problem I see is picking wood wide enough cover the
wood around the rim, but not so wide as to waste a lot.



Yeah, I edge joined two dog eared 1" x 6" x 6' old fence pieces, then
cut what I needed. I wasn't worried about waste as I had plenty of old
redwood. What wasn't used was tossed.

Thanks, this really helps. Although my wheel house will only be a little
over 2' wide, so I'll have to weigh it down accordingly.



I don't think you'll have to worry about weight much with a 2' wheel.

I see you're running your filters in parallel? What sort of filter media are
you using? My pond 'upgrade' is happening til the spring (we've already had
frost here), so I'm just planning the filter and getting ready to build the
wheel over the winter.



Just some bio-balls.

There is a "clarifier" before the pump at the other end of the pond. It
collects most of the heavy stuff. I use a course filter there. The
clarifier skims off the top and draws off the bottom drain keeping the
water moving and rich with oxygen.

The water stays really clear, the plants grow like crazy and so do the
Goldfish!!
